And it will take 16 years to start actually getting any return. Not to mention this will be GREAT for any car companies out there that can’t make money as it is. Like GM for example. But those are just details.

Using a 2007 base vehicle, the committee estimated the potential fuel savings and costs to consumers of available technology combinations for three types of engines: spark-ignition gasoline, compression-ignition (CI) diesel, and hybrid. According to its estimates, adopting the full combination of improved technologies in medium and large cars and pickup trucks with spark-ignition engines could reduce fuel consumption by 29 percent at an additional cost of $2,200 to the consumer. Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37 percent at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43 percent at an increase of $6,000 per vehicle.

…Hybrid vehicle technologies are one of the most active areas of research and development. The degree of hybridization can vary from minor vehicle stop-start systems to complete vehicle redesign. A fully hybrid vehicle could reduce fuel consumption by about 50 percent at an estimated price increase of up to $9,000 a vehicle depending on vehicle size. …
